Lucien moaned about his cock. That was what he wanted, to be used for someone else'd pleasure. It created his own pleasure. He wanted to make Nate moan more. Needed to hear that praise.
He moaned about the other's cock, sending vibrating down it. It would be a shame to let Nate come in his mouth, since Lucien had plans for them, but he wanted just be on his knees letting Nate fuck his mouth like he was made for it. He was made for it, this was the only think he was ever good at.
